Definitions

  • the invention relates to a protective device, in particular an impact protection device.
  • a protective device which can preferably be used in the industrial sector, has the aim of delimiting or protecting spatial structures or industrial plants against unwanted application of force by industrial vehicles or the like.
  • Limiting devices or passive guidance devices are known, for example, in road construction in the form of guardrail devices.
  • Barrier devices of this type are generally designed in such a way that the vehicle, in particular the person inside, is protected, and only secondly is the space located behind the crash barrier device. So that such a guardrail device can perform this protective function, the kinetic energy of the vehicle is converted into a deformation of the guardrail device in the event of an impact, in particular a large path of deformation of the guardrail allowing the vehicle to be safely intercepted.
  • guardrail devices So that the function of the known guardrail devices is ensured, they are equipped with predetermined breaking points which, in the event of an impact, enable the guardrail to be stripped from the post that supports them. Furthermore, the posts used in road construction are designed to be relatively soft, since they generally do not have an interception function.
  • guardrail devices can not be used as protective devices in the industrial sector, although they are manufactured in large numbers, so that cheap standard parts or components with sophisticated technology are commercially available.
  • the protective device according to the invention has a plurality of stands, each of which is formed from a base plate and a post attached thereon, and has a plank. These components forming the protective device are well known in road construction and can therefore be used unchanged and adapted for the protective device according to the invention. According to the invention, the plank is connected to the stand via a connecting element and is thus supported.
  • the special feature of the protective device according to the invention is that it has no predetermined breaking points and thus holds the plank down by means of the connecting element. This ensures that stripping of the plank from the stand is prevented.
  • the stand consists of a post and a support element
  • a self-standing component is created which facilitates the construction of the protective device.
  • the support element fixed to the floor with a screw construction forms a full frictional engagement with the floor, which absorbs shear forces parallel to the floor.
  • the fact that the stand is connected to the floor by means of a screw construction ensures that the positioning of the protective device can be handled flexibly, in particular if several anchors covering a certain area, in particular precast element anchors, are embedded in the floor. To redesign the area to be protected by the protective device, only the screw construction has to be loosened so that the protective device can be implemented.
  • the protective device Since the individual components of the protective device are matched to one another and interact as a whole, it is achieved that the forces applied in industrial use cannot separate the components forming the protective device. In this way it is achieved that the protective device has only a small deformation path after an impact.
  • the protective device can be installed in a space-saving manner directly and close to the industrial plants or the like, taking into account the expected deformation path.
  • the use of the connecting element holding down the plank makes it possible to modify conventional protective plank devices which are produced in large quantities in such a way that the deformation path decreases to a value which is acceptable for the industrial sector.
  • the connecting element is attached to the post with frictional engagement, the advantage is achieved that when the clamping holding force caused by the frictional engagement is exceeded, a relative movement of the connecting element can take place up to a stop provided on the post.
  • the deliberately induced relative movement of the connecting element hereby provides a type of buffer area in the resistance moment of the protective device, which weakens or does not permit overstressing of the components maintaining the connection of the protective device and their connections. Due to the fact that a plank is supported on several stands, tensile stress occurs inside the plank, particularly when the post is folded, which counteracts the application of force.
  • the protective device is given a kind of elasticity which avoids overstressing the connecting structures of the protective devices, in particular in the event of an impact impact. If the strength of the impact is so great that the connecting element executes the relative movement up to the stop provided on the post, a further positive connection is thus produced, via which the force can be introduced through the post into the ground.
  • the plank is connected to the stand via a connecting element with a frictional connection
  • an overall construction which is rigid when a force is introduced into the connecting element below a clamping holding force caused by the frictional connection.
  • the rigidity of the overall construction is generally designed such that a force exerted by persons, whether by leaning against it or by sitting on it, cannot cause the overall construction of the protective device to be deformed.
  • the advantageous development of the protective device according to claim 3 enables in a simple manner that in the event of an impact, the connecting element performs a tilting movement about an axis of rotation extending in the horizontal longitudinal direction, since it is fastened in a rotatable manner to the stand via a fastening element. This prevents the connecting element from twisting in the event of an impact and possibly breaking due to the twisting.
  • plank has a C-profile according to claim 5, which is slipped onto the stand or post, a plank that is frequently used is used on the one hand, and on the other hand a protective measure on the head side of the stand is brought about.
  • the protective device according to the invention has So no protruding protrusions causing injuries, so that industrial protection regulations can be easily fulfilled with this measure and the requirements of an appealing industrial design can be met.
  • the stiffening device follows the contour of the C-profile of the plank according to claim 6, with its ends projecting beyond the C-profile of the plank abutting against the stand, then a stiffness of the plank on the stand is achieved, which gives the protective device an additional Dimensional stability conveyed. Furthermore, if at least one spacer is introduced in the space between the stiffening device and the stand, the lateral flanges of the C-profile are additionally supported, so that a further possible measure for the shape stability of the plank is given.
  • the development according to claim 8 includes the advantage that commercially available semi-finished products with an I-profile can be used, and the flanges can simultaneously function as stops of the attached connecting element when the connecting element is attached to its connecting web. Elaborate, sometimes retrofittable stops on the stand, if it is designed, for example, as a square hollow profile, are therefore not required.
  • the path of the relative movement can be controlled in an advantageous manner via the ratio of the side length component of the connecting element running in the longitudinal direction of the stator to the smallest distance SP between connecting element 11 and stop AN.
  • connecting element according to claim 10 is designed with an L-profile, then again commercially available, easy-to-assemble semi-finished products can be used, which are nevertheless controlled with a minimum dimension Ensure power transmission. If such connecting elements have at least one through hole on each leg, then the connecting element can be non-positively connected to the stand or to the plank by means of screw or rivet connections. If the through holes of the connecting element are designed as elongated holes, there is the possibility of compensating for uneven floors or height differences or offsets between the stand and the fastening point on the plank.
  • the support element is preferably designed as a base plate, a good surface pressure can be achieved, which includes an advantageous introduction of force into the ground.
  • a commercially available precast anchor can be used, which can be embedded in the floor and can hold the footplate by means of a screw construction penetrating the through-hole, which is in engagement with the footplate.
  • the points of attack of the screws of the screw construction can be positioned on the footplate in such a way that the lever action with a lever arm that is formed between the screws and the tilting point of the footplate supports both the grip and the transmission of force into the ground.
  • the fastening elements used by the protective device can be part of a detachable connection in the form of a screw and bolt connection or part of a non-detachable connection in the form of a rivet connection.
  • commercially available fasteners are used again, so that the connections used in the protective device can be accomplished in a simple manner.
  • the interaction of all the components forming the protective device enables the force introduction into the ground to be carried out in a controlled manner.
  • the precast anchor is formed by an adhesive anchor, a force-transmitting connection is nevertheless established, in particular in the case of the soft floors which frequently occur in the industrial sector.
  • the protective device 1 has a stand 3 to which a plank 5 is attached.
  • the plank 5 is designed as a semi-finished product with a C-profile, which is placed over the head of the stand 3.
  • the plank 5 is provided on the inside with a stiffening device 7 which preferably follows the contour of the plank 5 and which abuts against the stand 3 at points A.
  • spacers 9 are introduced between the stiffening device 7 and the stand 3, which provide the plank 5 with an additional increase in dimensional stability by being supported on the stand 3.
  • the stiffening device 7 is connected to the plank 5, for example, at points B by means of fastening elements in the form of screws or rivet connections.
  • the plank 5 is fastened to the stand 3 via a connecting element 11, for example with an L-profile.
  • the connecting element 11 can preferably be connected to the stand 3 at point C with a fastening element in the form of a screw or rivet connection.
  • the fastening element is arranged in such a way that it is aligned essentially parallel to the longitudinal direction of the plank in order to form an essentially horizontal axis of rotation directed in the longitudinal direction of the plank.
  • two connecting elements as shown in FIG. 2, can optionally be attached to both sides of the stand 3, which rotate about the same axis of rotation.
  • the connecting element 11 is connected to the stand 3 so that there is a distance SP between the connecting element 11 and the stand 3.
  • the connecting element is preferably connected directly to the plank 5 at points D or, as shown in FIGS. 1 and 2, to the plank 5 via the stiffening device 7.
  • the stand 3 in turn can be formed from a post 13, preferably in the form of a semi-finished product with an I-profile, which can be fastened on a support element 15, preferably in the form of a base plate 17.
  • the attachment can be accomplished on the one hand by means of a releasable connection in the form of screw connections, which cooperates with the post 13 and the foot plate 17 by means of an intermediate piece (not explained in more detail), and on the other hand by means of welding.
  • the base plate 17 can be non-positively via fastening elements 19 with a commercially available prefabricated anchor 21 embedded in the floor BD, for example in the form of an adhesive anchor formed from an anchor rod or a sleeve with a thread, for introducing the forces acting on the post 13 into the floor BD get connected.
  • a pre-fabricated anchor matched to the protective device offers the possibility of connecting the protective device to relatively soft floors that are often found in the industrial sector.
  • additional stiffening elements can preferably be provided between the posts.
  • FIGS. 3 and 4 are intended to illustrate the mode of operation of the protective device according to the invention.
  • FIGS. 3 and 4 represent a perspective view of the protective device before and after the application of force, as they have been determined by the tests which follow the invention.
  • the force is transmitted to the stand 3 via the impact system contacts A. If the moment of resistance of the stator 3 is less than the application of force, the stator 3 begins to yield in the direction of the application of force. As the stand yields, tensile stress occurs in the plank attached to other stands. This tensile stress acts on the force opposite. Furthermore, if the tensile stress generated by the application of force is greater than the clamping-holding force caused by the connecting element, the connecting element attached to the fastening point C begins to rotate, as a result of which energy is consumed or destroyed via the frictional connection between the stand and the connecting element.
  • the connecting element carries out the rotary movement until the force which causes the rotating or tilting movement and counteracts the force applied, caused by the tensile stress of the plank, is no longer greater than the frictional force or until the connecting element strikes the stop AN of the stand. After the connecting element has struck the stop, a new positive connection of the protective device has been established and the force is dissipated via the stand.
  • FIG. 5 shows, for example, a connecting element 11 in the form of a semi-finished product with an L-profile.
  • the through holes designed as elongated holes are clearly visible in this illustration.
  • the single elongated hole on one of the legs is used for the rotatable fastening on the stand, the double elongated holes, however, are used for the non-positive fastening of the connecting element with the plank.
  • the connecting element which is preferably made of weldable, hot-dip galvanized steel with a thickness of at least 8 mm, can be fastened, for example, with screw construction of the quality 5.6 or 8.8.
  • This post is inserted through a base plate with the dimensions 300x300x20 and welded on both sides.
  • the base plate is fastened to the building with a concrete floor of concrete strength class B35 using four M16x55 screws of quality class 5.6 provided in the corner areas of the base plate.
  • This post is butt welded onto the base plate of example 1.
  • anchor rods M16 of quality class 5.6 are provided, which hold the base plate on the structure by means of corresponding nuts which engage with the anchor rods.
  • anchor rods M16 of quality class 8.8 are provided, which hold the base plate on the structure by means of corresponding nuts which engage with the anchor rods.
  • the protective device according to the application is arranged and fastened on a softer concrete floor that is frequently encountered in industrial areas with a concrete of strength class B25, it is advantageous to fasten the post to a footplate, preferably with the dimensions of at least 400x250x15 and in addition to the four in the corner areas
  • the screw constructions provided for the base plate provide a further screw construction, preferably in the middle between the two screw constructions, which face the application of force.
  • This additional screw construction can have components of the same or a lower quality than the two have adjacent screw constructions. With this additional screw construction, it is achieved that, on the one hand, it is possible, even on softer floors, to achieve an adhesion of the protective device to the floor which corresponds to the adhesion to a harder floor of strength class B35.
  • the connecting element for example, as a semi-finished product with a double T profile (TT), which receives the connecting web of the stand provided with an I profile between the legs.
  • TT double T profile
  • the stand or only the post of the protective device can be slightly inclined against the direction of the force application, the post preferably being connected to the base plate by a round weld. The latter harbors further bond stability.
  • the connecting elements can be designed in their geometrical shape in such a way that the side surfaces of the connecting element striking the stop could be flattened in order to bring about better contact with the stand and thus better power transmission.
